1 '0 all whom it may concern:

Be it known that I. Eowxnn H, ANGIER, a citizen of the United States, and a resident of Framingham, in the county of Middlesex and Commonwealth of Massachusetts, have invented an Improvement in Machines for Reinforcing Paper and other Material, of

Figure 1 is a side elevation of the mecha- Fig. 2 is an end elevation as seen from the left of Fig. 1;

Fig. 3 is a plan; and

Fig. 4 is a central longitudinal. section of a portion ofthe mechanism parts being broken away.

Referring to Fig. 1 of the drawings, in

the embodiment of the invention shown there is provided aframe 1 having upper and lower presser rolls 3 and 5 mounted thereon. A sheet of paper 7 is led past a series of guide rolls 9 and a smaller guide roll-11 to and between the presser rolls 3 and A second sheet of paper 13 is led over a guide roll "15 between the lower presser roll 5 and a roll 17 mounted beneath the same and thence between the presser rolls 3 and 5. A vat 19 beneath theroll 17 contains liquid black asphaltum or other suitable adhesive. The roll 17 revolves through the vat and applies the adhesive to the sheet 13. The arrangement is such that the sheets of paper meet between the presser rolls with the-adhesive layer between and securing the sheets together. The abovedescribed parts may be of usual well-known construction and therefore need not be described more in detail herein.

I shall next describe the mechanism for applying the reinforcing threads to the paper. The mechanism here shown is mounted on a base 21, preferably U-shaped in form,

and having bearings receiving trunnions 23 of a standard 25. This standard may be rocked on its trunnions to different positions of adjustment and be held by screw bolts 27 and caps 29 which engage the bearings. To limit the adjustmentof the standard, it may be provided with lugs 31 to engage shoulders 33 projecting from said base bearings.

For supplying the thread or other reinforcing material for reinforcing the paper, I here show a rotary creel comprising a disk plate having spool-supporting spindles 37 projecting from one face thereof, said plate being mounted. as best shown in Fig. 4, on a hollow shaft 39 (in effect a hub for the plate 35) journaled on a sleeve 41 fast in boss 43 at the upper end of the standard 25. The hollow shaft may be confined against axial movement at one end by engagement with the end of said boss, and at the other end by'a cap 45 threaded on the sleeve. To guide the thread conducted-from the thread spools, a second disk plate 47 may be provided having suitable eyes 49 for receiving the threads. This disk is mounted fast on the hollow shaft and rotates therewith.

I shall next. describe traversing mechanism for laying the threads transversely to the length of the paper sheets. For this purpose the threads may be led from the guide plate 47 through eyes 51-on a sprocket chain 53 trained over sprocket wheels mounted at the ends of a bar 57 which extends longitudinally of the paper feed rolls and closely adjacent to the bite between them. The eyes'onth'e chain are moved through a sub stantially elliptic path markedly oblate and relatively long as compared with creel 35. T he threads are, therefore. guided approximately into the plane of the paper and laid out across the same. To support the bar and chain in this position, the former may be provided (see Fig. 4) with aboss 59 faston a tubular arm 61 projecting into a sleeve 63 which rests upon the lower surface of the fixed sleeve 41 referred to andiswelded or otherwise secured thereto.

I shall next describe a suitable'train by which the creel and sprocket chain 53 may be driven from a motor 65 here shown 4 as mounted on a bracket 67 secured to the lower end of the standard 25 inferred to.

. The rotor of the motor 65 (see Fig. 1) has arm 81, best shown in Fig.

ings in the standard. Also on this shaft is a pinion 75 meshing with a gear 77 fast on a shaft 79 directly above the shaft 73 and journaled in bearings on the standard. The shaft 7 9extends rearwardly from the standard and is supported by an L-shaped 3, fast on said standard.

To rotate the creel from .the shaft 7 9 the latter is provided with a pinion 83, seen at the right of the standard in Fig. 1, meshing with a gear 85 fast on the hollow shaft 39 which carries said creel. I

To drive the sprocket chain from the shaft 79 the latter is provided with a gear 87 splined thereon and meshing with a pinion 89 fast on the shaft 91 which is journaled in a bearing in the arm 81. This shaft as seen in Fig. 4 projects forwardly through the tubular arm 61 and its forward end is journaled iri'the boss 59 of the sprocket chain supporting bar. A pinion 93 fast on the shaft 91 is located between the upper and lower runs in the sprocket chain and engages the former to drive said chain.

Thus it will be apparent the creel and sprocket chain may be driven by a very simple transmission mechanism in different orbital paths.

When the'machine is operating to apply thereinforcing threads to the paper, the traversing chain should be located closely adjacent-to the rolls in order that it may maintain the desirable positive iidance and control over the threads. owever, there is a limit to the closeness with which the traversing chain can be adjusted to said rolls and to provide furthercontrol over the threads, fingers 94 may be secured to the sprocket chain at points corresponding to the thread guiding eyes 51 thereon. These fingers may extend so close to the bite between the rolls that there is no opportunity for the threads to be diverted from their proper accurate positions on the paper. I may also provide guide bars 95 supported in sockets 96 on the side franres 1 (see Fig.

3) and. defining between them a narrow thread receiving slot parallel to the bite of the rolls. The bars 95 may be set in between the overhanging parts of the rolls and closeto their line of contact. By this means the threads are held spread out in a plane and so delivered to the paper.

The sprocket chain preferably extends somewhat beyond the ends of the paper feed rolls and therefore the threads will be ourried out beyond the width of the paper sheet in the course of their traverse. To insure proper location of the bights of the thread relatively to the edges of the paper,

the threads on reaching the edges may be engaged by guides 97, here shown as r ods mounted on the side frames 1 and having portions closely conforming to the surface,

of the rolls. The cusp or point of this portion will engage the thread and guide the bight which would otherwise project beyond theed e of the paper into parallelism therewith. The bights of successive threads thus disposed may overlap and form a sort of selvage. To facilitate insertion of the threads through the eyes of the sprocket chain and its fingers and to permit ready access to the paper rolls and the adhesive containing vat, it is desirable to draw the traversing mechanism away from the rolls. The support of the traversing mechanism on the tubular arm 61 lends itself advantageously to this purpose. The tubular arm may slide axially in the fixed sleeve63. To shift the tube it may have a ring 101 (see Fig. 1) fast thereon, the ring being connected by a link 103 with a hand lever 105 pivoted at its lower end on the motor bracket 67. This lever has a spring-pressed hand grip 107 pivoted thereto provided with a dog 109 for engagement with lock notches 111 in the curved arm 113 connected to the'standard 25 and the bearing arm 81 referred to. The ring 101 may be connected by a yoke 115 with the hub of the gear 87 (Figs. 1 and 1). When it is desired to adjust axially the sprocket chain driving shaft and the tubular arm receiving the same to present the traversing chain to different fixed operative positions or to withdraw the same from operative position to facilitate threading thereof or for purposes of adjustment or repair, the entire arm 61 and the mechanisms carried thereby may be moved longitudinally by means of the hand lever 105. It will be observed that the gear 87 slides along its shaft 79 with the pinion 89 and is adapted to rotate the latter and drive the sprocket chain when the latter is in its different positions of adjustment.

In some cases, to furnish furtheraccess to the paper feeding and coating mechanism, it may be desirable to further withdraw the traversing mechanism therefrom. To accomplish this, the standard holding screw bolts 27 may be loosened and the standard'and the parts supported thereby may be bodily tilted backwardflup from the vertical, lifting the bar 57 and its associated mechanisms u1.)\vardly clear of the, rolls 3 and 5. The screw bolts may be then tight ened to hold the mechanism in this position. Thus by an extremely simple adjustment the entire mechanism may be quickly and easily moved out of the way of the paper feeding and coating devices.

In'same cases it is desirableto apply longitudinal reinforcing threads to the sheets in addition to the transverse threads. To accomplish this, a creel may be placed at any suitable location at the rear of the traversingmechanism and threads 117 may be led from spools thereon to the crescentshaped space 119 (see Figs. 2 and 4) between the fixed sleeves 41 and 63. The threads pass through this space and emerge from the forward end thereof, diverge outward and enter a series of guiding eyes 121 in the sprocket chain supporting bar.

In operation the longitudinal and traversing threads are conducted from their supply spools and threaded through their guides as described. They are then manually introduced between the paper sheets of the bite between the presser rolls. The rotation of these rolls' will readily draw the threads therebetween and the driven sprocket chain will lay the transverse reinforcing threads accurately and effectively in their transverse runs. It will be apparent that the angle of these transverse threads to the edge of thepaper sheet may be'varied by relating the speed of rotation of the presser rolls as desired.

The mechanism for applying the transverse and longitudinal threads is a separate unit from the paper feeding and coating mechanism, and therefore may be readily applied to standard mechanisms now in use without alteration thereof.

It will be understood that while the mechanism has provision for introducing longitudinal reinforcing threads to the sheets, in some cases it may be desired to omit such threads and apply merely the transverse reinforcing threads to the sheets.
